* breakpoint.c, findvar.c, infrun.c, putenv.c, stack.c: Fix
miscellaneous comparisons of integer with NULL that elicit
compiler warnings about comparison of integer with pointer, when
NULL is ((void *) 0) rather than just a bare 0.
Tue Dec 10 04:07:22 1991 K. Richard Pixley (rich at rtl.cygnus.com)
* Makefile.in: infodir belongs in datadir.
Sun Dec 8 21:13:33 1991 Michael Tiemann (tiemann at sphagnum.cygnus.com)
* symtab.h (struct fn_field): Add new fields `is_private',
`is_protected', `is_stub', making room by reducing the size of
`voffset'.
(struct fn_fieldlist): Delete the fields `private_fn_field_bits'
and `protected_fn_field_bits'.
(TYPE_FN_{PRIVATE,PROTECTED}_BITS): Deleted.
(SET_TYPE_FN_{PRIVATE,PROTECTED}): Deleted.
(TYPE_FN_{PRIVATE,PROTECTED}): Deleted.
(TYPE_FN_FIELD_{STUB,PRIVATE,PROTECTED}): New macros.
* valops.c, valprint.c, symtab.c: All callers updated.
* buildsym.c (read_struct_type): Delete the `visibility' field
from `struct next_fnfield', and rework code so that visibility
info is stored into the fn_field directly. Also, hacked to set
TYPE_FN_FIELD_STUB for both static and normal member functions.

* i386-tdep.c: Fix a problem on i386 systems where buffered code
